硅卡醇（一种真菌来源的植物毒性二倍萜）的结构在化学转化后通过核磁共振波谱进行了分析。 Siccanol 被发现是从 Ar-thrinium sp. 中分离出来的 terpestacin 的差向异构体，因此被重新命名为 11-epiterpestacin。其立体化学也与 fusaproliferin 相同，fusaproliferin 是一种结构相关的来自 Fusarium proliferatum 的霉菌毒素。因此，该二倍半萜也可称为24-脱乙酰基镰刀菌素。 11-epiterpestacin的植物毒性几乎与terpestacin相同，但显着高于fusaproliferin。
The structure of siccanol, a phytotoxic sesterterpene of fungal origin, was analyzed after chemical conversion by NMR spectroscopy. Siccanol was found to be an epimer of terpestacin that has been isolated from Ar-thrinium sp., and was thus renamed 11-epiterpestacin. Its stereochemistry was also identical with that of fusaproliferin, a structurally related mycotoxin from Fusarium proliferatum. Therefore, this sesterterpene may also be referred to as 24-deacetyl fusaproliferin. The phytotoxicity of 11-epiterpestacin was almost equal to that of terpestacin, but significantly higher than that of fusaproliferin.
